  • Patent number: 11501346
    Abstract: Customers are identified as they enter a store and linked to one or more items previously ordered on-line. A route through the store to retrieve the ordered items is generated and sent to the customer's mobile device for display. The customer's movements are tracked as he/she goes through the store to retrieve products, and the location of the customer determined whenever he/she selects a product from the shelves. Based on whether the locations of the customer when he/she selected the products matches the predefined locations of the items ordered on-line, the customer is directed to go to one of an audit station or checkout lane, or alternatively, to bypass both audit station and the checkout lane and exit the store. In the latter case, the customer's account is automatically charged for the total cost of the ordered items.

  • Publication number: 20220312549
    Abstract: The present invention discloses a system and a method of walkie-talkie communication crossing various wireless frequency domains. The system includes walkie-talkies, communication servers, and a connection network connecting the communication servers for mutual communication. The walkie-talkies are divided into communication groups, and each communication group is assigned to one specific communication server. The walkie-talkies and the communication server in the same communication group employ an exclusive wireless channel to wirelessly communicate. In particular, the communication server is invoked by one of the walkie-talkies in the same communication group to perform a broadcasting process for the walkie-talkies in different communication groups to broadcast at the same time. The present invention is suitably applied to any indoor or outdoor environments as long as the communication servers are provided.

  • Publication number: 20220295540
    Abstract: A method for a user equipment (UE) to monitor a physical downlink control channel (PDCCH) is provided. The method receives, while being in a radio resource control (RRC) CONNECTED state, from a base station (BS), an RRC release message that includes a small data transmission (SDT) configuration. After receiving the RRC release message, the method transitions to an RRC_INACTIVE state from the RRC_CONNECTED state in response to receiving the RRC release message. The method then initiates an SDT procedure based on the SDT configuration. The method further determines whether a search space set associated with an SDT search space is received from the BS. The method monitors the PDCCHby monitoring the search space set during the SDT procedure when the search space set is received from the BS.
